Luckily, Dad had a proper slide-hammer nail extractor tool (that I
wouldn't have know existed if he hadn't had one) and that got most of
them out without too much hassle.

They do quite a bit of damage to the board, though.

They do ... to the top, dents either side of the nail head etc, but
that's it, no splitting of the boards when forcing them up from the
side with a bolster etc.

All removed now replaced with screws.

The larger head hopefully covering up the damage. ;-)

It does, mostly but even if it doesn't, I cant see an issue or think
of a better solution that didn't cause any worse damage?
